Answer

To add or subtract fractions, they must have the same denominator. If they do not, make the least common multiple of all of the denominators the new denominator. After adding or subtracting, reduce your answer.

When giving the fractions like denominators, whatever number you multiply the old denominator of a fraction by, you must also multiply it by the numerator.
